Applicatigm itled April 19, 1936. 1 Serial, oaaya Thi inyentig n, relates to ayehicle radiator heater. i

In driving automobiles during cold weather, it is the usual practice to cover the radiator and to thus prevent excessive cooling. However, it is a well known fact that the covers usually become loosened or otherwise give trouble, and .are more or less unsightly.

This invention is, designed to overcome the defects noted above, and objects oft-his invention are to provide a heater for the radiator which may be instantly thrown into operation by the simple manipulation of a rod or lever or as quickly cut out, and which will insure the proper heating of the radiator in the coldest weather without the use of a blanket or covering shield for the radiator.

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a diagrammatic View partly in section illustrating the device in its relation to the exhaust manifold and radiator, such view showing the cover of the box removed.

Figure 2 is an enlarged transverse sectional view of the device.

Figure 3 is a view from the rear of the attachment.

Referring to the drawings, it will be seen that the usual radiator 1 has been illustrated as well as the exhaust manifold 2. This exhaust manifold normally discharges through the exhaust pipe 3 to the mufi ler 1, and from thence to the rear of the machine. A valve 4 is interposed between the exhaust manifold and the exhaust pipe 3, and such valve is provided with a flap or valve proper 5 which may be rocked to either of two extreme positions, or may assume an intermediate position. This flap is carried in any suitable manner as by means of the rocking shaft 6 to which an external lever 7 is attached. This lever is operated through the medium of a control rod 8 which passes to any point easily accessible to the driver. The valve 4 has a forwardly extending opening which receives the forwardlyv extending pipe 9. This pipe leads to the front of the machine and has its flange 10 attached to the bottom of a box 11 secured to the front of the radiator. Preferably, the box is provided with a pair of side ears 12 which are bolted to theears 13 of the radiator as shown in Figure 1. It is provided with a having a plurality et; a ertures, '15; t lierimlziritlis. provided with a cover or front"16 as shown inFigu're' Within the box, a pipe 17 is positioned and has its flange secured to the bottom of the box. The pipe 17 communicates through an aperture in the bottom of the box with the p1pe 9 as shown in Figure 1. The pine 17 may be of a smaller size than the pipe 9 if desired. It is coiled into one or more loops wlthin the box 11 and discharges into a muf-, Her 18 carried within such box. From the mufiier, the products of combustion pass outwardly through the discharge pipe 19 extending downwardly from the box.

Under normal conditions, when average temperature exists, the products of combustion will be discharged from the exhaust manifold through the exhaust pipe 3 by properly setting the valve. However, durmg cold weather, all or a part of the prod- 'ucts of combustion will be passed through the p1pe 9 to the pipe 17. This pipe 17 will heat the interior of the box 11 and the heat Wlll not be communicated to the radiator.

It is to be noted that the heat is imparted to the lowest portion of the radiator which is the coldest portion thereof, and consequently,

by properly adjusting the valve, it is an easy matter to maintain the ideal temperature for perfect operation.

It will be seen that an extremely simple device has been provided of novel construction, which will maintain the temperature of the clrculating water at the ideal temperature irrespective ofweather conditions, thus permitting free driving of the car without a blanket or shield even in the most severe weather.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limitin as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

We claim:

1. In an automobile, the combination of an exhaust manifold, a radiator, a heater for said radiator comprising a box having an apertured rear portion and attached tov through said box, and a mufiier carried within said box and discharged downwardly through the bottom of said box.

2. In an automobile, the combination of an exhaust manifold, a rearwardly extending exhaust pipe, a forwardly extending pipe, a valve interposed between said exhaust manifold and said pipes and adapted to direct the products of combustion into either of said pipes, a radiator, a metal box secured to the lower front portion of said radiator and having communication with said radiator through its rear side, said forwardly extending pipe passing through said box, a muffler carried within said box and communicating with said forwardly extending pipe, and a discharge pipe leading from said muflier and discharged through the bottom of said box. g p a In testimony that we claim the foregoing we have hereunto set our hands at Manitowoc, in the county of Manitowoc and State of Wisconsin.
